Tractor-Harrow-Operating Mechanism, of My improved operating device may be which the following is a specification. used to operate-a single harrow or two of My invention relates to new and useful the same or different kinds when connected improvements in means for manipulating one behind the other. In Fig. 1 of the drawthe operating levers of tractor harrows, diings I have shown a common form of disk rectly from the seat of a tractor, when conharrow as the front harrow and aspading nected thereto. 1 harrow as the rear harrow, while in Fig. 2 The purpose of the invention is to pro- I have shown the invention applied to two vide simple and inexpensive means for operdisk harrows which are alike in construcating disk, spading or other forms of hartion. rows when connected to be drawn by a Referring in detail to the characters of tractor; to provide means whereby the tracreference marked upon the drawings, 5 tor operator may shift and angle the gangs represents a pair of tractor wheels, 6 an of harrows, with respect to the draw-beams, axle casing and 7 a draw bar cap to which so that the cutting disks of they rear gangs. the forward harrow is detachably concan be made to follow behind those of the nected. 8 represents the tractor seat mountfront gang while traveling over the road ed upon the tractorf To the draw beam 9 and between fields or angled as required of the forward harrow are attached links when harrowing; to provide a device-of the 10 and 11 and whose outer ends are conabove sort which can be readily'applied to nected to a clevis 12 whichin turn is bolted standard makes of harrows now in use, to the draw bar cap? of the axle casing, whether the sets of gangs are flexibly or and which serves as the operative connecrigidly connected, without materially alter tion of the harrow to the tractor. ing or changing their design; and finally Upon the forward end of this beam 9 to design the construction so that the same are also provided upwardly disposed standmaybe connected in the usual way, to comards 13 that are provided with braces 14 mercial forms-of tractors.

in the scope of the claims may be resorted to without departure from the spirit or sacrificing any of the advantages 'of the in- I vention. a

Similar characters of reference denote like or corresponding parts throughout the to a tractor and provided with my: im-.

several figures of the accompanying drawings forming a part of this specification,

and upon which.

Figure 1 shows a perspective view of a disk harrow and spading harrow flexibly connected together intandem and attached against turning but pivoted at 20 to a stud upon the table 15 and is provided with a notch21 that engages one of a series of teeth on a segment. 22 upon the shaft 17 to hold the same disconnected by one hand of the operator while he turns the wheel with the other.

I Braces 23 connect the forward .end of the draw-beam with the cross bar 24 secured 'tothe underside of the draw-beam. The 105 nected at 26 to the arms 27 and 28 carried 1 10 which may be readily by the cross bar. This leaves each gang of disks free to be swung upon the said pivots to the saidshafts and whose forward ends are also pivotedly attached to the lower ends of the operating levers 30 and 31 respectively. These levers are pivotedly attached to the draw-beam 9 at 32 and their upper ends are connected together by a rod 33 and the lower ends are similarly connected by a rod 34 so as to insure a like forward and backward operation of the two levers simultaneously and for the purpose of shifting the angle of the gangs of disks with which they are connected.

The draw beam 35 of the rear harrow is swivelly connected to the rear end of the front draw-beam at 36 in a way to form a flexible connection between the two. The operating levers 37 and 38 of the rear harrow have their upper ends, as well as their lower ends, connected together by rods 39, in a similar manner to the before mentioned levers 30 and 31. These rear levers are pivoted to the draw-beam 35 at 40 and are adapted to be swung forward and backward. The forward endsof the links 41 are pivotedly connected to the lower ends of the levers 37 and 38 while the rear ends are similarly connected "to the inner end portions of the shafts 42 upon which the disks 43 are mounted. The braces 45 extend out from the draw-beam 35 and are connected to the studs 44 mounted to turn in a bearing 44 supporting the outer ends of the rear gangs and which are adapted to be adjusted forward and backward similar to the gangs of the forward harrow through the movement of the operating chain 48 and its actuating means.

Upon the rear end of the draw-beam 35 is provided standards 46 that carry an idler wheel 47 over which the operating chain 48 is guided. The upper section of this chain is connected with the rods 33 and 39 so as to move the same'and the levers in which they are mounted. The forward end ofthe upper section of the chain is connected with and over the top side of the.

shaft 17 while the other end of the chain is connected to wind upon the under side, thereupon it will be seen that when the shaft is turned in one direction one end of the chain is wound on the shaft, and the two sets of levers moved in'one direction, whereas if the shaft is turned in the oppo: site direction the other 'end is wound on, and the levers shifted in the opposite direction. Either of these operations would-tend tc. shift the relative position of the four gangs in unison, whereas withthe cross chain connection 48 as shown in Fig. 2 the condition would be reversed, with the result that the inner ends of the forward gangs of disks would be moved rearward simultaneously with the forward movement of the inner ends of the sections of the rear harrow so as to angle the same as indicated in Fig. 2. On the other hand if it is fde sired to position the gangs parallel or atanthrough the shaft and chain connections. would shift the levers in a manner-to bring I about the desired change.

Having thus described myinvention, what I claim and desire to secure by Letters Pat-' ent, is '1. The combination with the draw-beam of a tractor ha'rrow having levers and con-- nections for angling the gangs of disks, of a shaft carried upon the draw-beam adjacent to its point of attachment to a tractor, and provided with operating means, and a chain connecting the shaft with the levers for operating the same to shift the gangs of disks.

2. The combination with the draw-beam of a tractor harrow having levers and connections for angling the gangs of disks, of a support carried thereon adjacent to its point of attachment to a tractor, a shaft mounted on the support and provided with operating 'means, and a chain connecting the shaft with the levers for operating the same to shiftthe gangs of disks.

3. The combination with the draw-beams of a pair of tractor harrows' coupled together one behind the other, and having levers and connections for angling the gangs of disks, of a shaft carried upon the drawbeam of the forward harrow adjacent to its point of attachment to a tractor and proharrows for operating the same to shift the gangs of disks of the two harrows simultaneously.

4. The combination with the draw-beam of a tractor harrow having levers and connections for angling the gangs of disks, of a support carried thereon adjacent t6 its point of attachment to a tractor, a shaft mounted on the support and provided with operating means, anidler carried upon the draw-beam, and a chain connecting the shaft with the levers and guided over the idler for operating the levers to shift'the gangs of disks.
